Abstract
A system for securely producing and using high-entropy security information, such as a password. The system includes a printer, a display device, and a generator computer that is connected to the printer and the display device. The generator computer generates the high-entropy set of characters, (e.g., password), and also generates a machine-readable representation of the high-entropy set of characters, (e.g., a barcode). The generator computer causes the printer to print the high-entropy set of characters and the machine-readable representation on paper, and then deletes the high-entropy set of characters and the machine-readable representation from the system. The high-entropy set of characters, (e.g., password), may be entered into a target computer by scanning the barcode on the paper using a barcode scanner connected to the target computer, which is significantly faster than, and eliminates the human error associated with, typing in a high-entropy set of characters.
Core Innovation
A system and generator computer generate a high-entropy set of characters and generate a machine-readable representation that represents the high-entropy set of characters. The system provides the high-entropy set of characters and the machine-readable representation to a printer for printing on paper.
After printing, the system deletes the high-entropy set of characters and the machine-readable representation. Deleting the high-entropy set of characters and the machine-readable representation comprises directing the printer to delete the high-entropy set of characters and the machine-readable representation after the printing.
The document further describes the machine-readable representation as a barcode or a quick response (QR) code, and describes optional display and user interaction for the high-entropy set of characters. The document also includes a key check value (KCV) based on the high-entropy set of characters, and documents using a printed machine-readable representation to input the high-entropy set of characters into a target computer.
Claims Coverage
The independent claims are clm-00001, clm-00017, and clm-00022. Across these independent claims, there are three core inventive feature groups: generating high-entropy security information and a machine-readable representation, printing both on paper, and deleting the generated information by directing the printer after printing.
Generating high-entropy set of characters and machine-readable representation
Generating a high-entropy set of characters; generating a machine-readable representation that represents the high-entropy set of characters.
Printing on paper with a printer
Providing the high-entropy set of characters and the machine-readable representation to the printer for printing on paper; printing the high-entropy set of characters and the machine-readable representation on a paper using a printer.
Deleting after printing by directing the printer
Deleting the high-entropy set of characters and the machine-readable representation; deleting the high-entropy set of characters and the machine-readable representation comprises directing the printer to delete the high-entropy set of characters and the machine-readable representation after the printing.
The independent claims cover generating a high-entropy set of characters together with a machine-readable representation, printing both on paper via a printer, and securely deleting the high-entropy set of characters and the machine-readable representation after printing by directing the printer to delete them.
